- Application fled July 12,

To all whom it may concern:

Be it known that 1, ROBERT S. HALL, a citizen of the United States, residin at Corning, in the county of Steuben and tate a of New York, have invented certain new .and useful Improvements in Radiator or Other Caps, of which the following is a specification.

This invention has reference to caps for radiators or gasoline tanks or the like, and its object is to provide a self-closing cap for. the purpose which will hold its position against displacement under normal conditions of use and at the same time avoidis ing the necessity of employing screw threads tohold the cap in place.

In an automobile radiator, the cooling tank is provided with a ca which is usually screwed into (place, and w enever the radiator is emptie or filled, the cap must be unscrewed and subsequently screwed into place, and the same is true with respect to a gasoline tank where leakage cannot be tolerated.

In the filling tubes of radiators and gasoline or other tanks, the cover member or plug is customaril screwed into place, but in accordance wit this invention, the cap is so constructed that it will automatically move into tight relation to the filling tube,

so closing the same and preventing evaporation or other losses of the contents.

In an automobile, it is not infrequently the ex erience that steam is generated in the ra iator and some pressure may there is not a screw threaded cap, will force t e cap open. In

the case of the gasoline tank considerable pressure may occur due to eva oration of the gasoline and the efiect of t 0 pressure as due .to evaporation must be counteracted to avoid losses.

In accordance with the invention, the fill: in tube may so dered or riveted into place and a clos- 6 ing cap is provided with a hinge connection between the cap and the filing tube. The cap is rovided with a gasket serving to practical y hermetically seal the junction of the ca and the filling tube and the cap is rovi ed with a cam coactin with a spring which will snap and hol the cap in closing position or term orarily hold the cap in the open position, t e spring PI'OVIding sufiicient pressure against the internal as pressure in the radiator or can to overcome be of usual construction,

of this specification, with t e understanding that the invention is not confined to any strict conformity to the showing of the drawings, but may be changed and modified so lon as such changes and modifi-- cations mar no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a p an view of the cap, which for convenience of description may be considered as a radiator cap of an automobile.

Fig. 2 is a vertical section of the radiator cap and filling tube with the cap in the open position.

Fig. 3 is a section on the line 3-3 of Fig. 1.

ig. 4 is a rear elevation of the radiator ig. 5- is a plan view of the filling tube and the ring for supportin the radiator ca the latter being omitted rom the figure.

eferring to the drawings, l-indicates a filling tube for an automobile radiator or a container, and which has secured therewith, in proximity to its upper end, an annular member or ring 2, w ich is provided with a pair of laterally disposed parallel spaced wings 3 havin the inner termini thereof formed integra termed a coupling bar 4, which is flush with the outer edges of the win s 3 and body of the ring 2, and the lower face of the bar 4 is spaced above the lower edges of the wings 3. The bar 4 not only constitutes a coupling means to form the annular member of one piece, but also constitutes an abutment for the inner end of a spring 7 to be hereinafter referred to. Each of the wings 3, at its outer end, is provided with a curved en lar ement which projects above the upper on of the tube 1, and said enlargements are indicated at 3".

Spanning the space between the enlargements 3, as well as having its ends secured in said enlargements, is a pin 5 which constitutes means for hinging a cover 6 to the win 3. The cover 6 is ormed with a depen ing annular rim 6' of a diameter to exwith what may be tend over and project from the upper end of the filling tube 1. The rim 6* is cutaway as at 6 to provide a clearance for the wings 3, when the cover is shifted to closed position, as well as to open position, as illustrated in Figures 2 and 3 of the drawings. The cover 6 is provided with a lining 6 of rubber or other suitable composition of a character to withstand to an extent the efiects of heat when the cover is employed to close the upper end of the filling tube of a radiator or to withstand the efiectsa of gasoline or other like material when the cover is used in conjunction with the gasoline tank or the like.

Fast between the brackets 3 is a spring 7 carried by a in 4 and bearin at its inner end against t e bar Fund at t e other end reaching to near the outer end of the wings 3. The cover 6 is provided with an extension 7 at one side forming one member of a hinge and through whichextends the pin 5 whereby the cover is pivotally connected with the enlargements 3 of the wings 3. The extension 7 is of a width to project in the space formed between the wings 3 when the cover 6 is shifted to open position. Formed integral with the inner face of the extension 7, at a point inwardly with respect to the free end of said extension-'7, is a cam 8 positioned in the path of the outer end of the spring 7. The cam end is so related to the spring 7 that when the cover is opened, the spring will prevent the free end of the extension 7 and the cover from closing and when the cover is closed, the cam will engage the spring and lock the cover in closed position against opening under ,;ordinary conditions of use.

In order to cause the cover 6 to make a ti ht fit with the upper end of the filling tu' e 1, such upper end 'is' machined or smoothed so as to bear evenly against. the rubber lining 6* on the coveri- At the side of the cover 6 remote from the cam 8 there is provided a manipulating handle 9 by means of which the cover may be moved to the open position;

What is claimed is 1. In a can for automobile radiators and the like, a filling tube, 'a ring carried exteriorly of the outer end of the filling tube, and rovided withoutwardly disposed radial in e members, a fiat spring 10d ed between t e hinged members below t e top thereof, and a cap for the outer end of the filling tube carrying a cam at one end in position to engage the spring, a sealing gasket in position to engage the end of the filling tube and a handle member on the side of the cap remote from the hinge.
